Benefits of technology

The present invention provides a lamp assembly that reduces glare. It includes a plurality of LED light sources and a reflector positioned above them. The reflector has multiple reflective segments that are lit up by each LED light source. The reflector removes the directionality of the light emitted from the LED light sources to reduce glare. The technical effect of this invention is to produce a lamp assembly that reduces glare.

Problems solved by technology

As the power of the LED increases, the brightness can increase to a level whereby an uncomfortable glare is experienced by a person viewing the LED directly.
In the past, lamp assemblies that have been used to provide ground illumination have achieved the required level of brightness but in the process created too much unwanted glare.
To reduce the glare, a lower power light source would have to be used which compromises the ability of the lamp assembly to appropriately illuminate the ground area.

Embodiment Construction

[0040]Referring now to FIG. 1, there is shown a lamp assembly 10 for a vehicle. The lamp assembly may be integrated into an exterior rear view mirror (side mirror) assembly of a vehicle. In one form, the lamp assembly provides a ground illumination light configured to illuminate a ground segment adjacent the vehicle (the lamp assembly 10 is preferably installed in both a left and a right hand side mirror of the vehicle for this purpose). The ground illumination light may illuminate an area approximately 3 m out from the side of the vehicle and is used for general illumination, such as when a user is setting up a camp site or changing a tyre.

[0041]The lamp assembly 10 has a housing 20, a reflective moulding 30 mounted into the housing (see FIG. 4B) and a lens 100 external to the housing covering the reflective moulding 30. The lens 100 is connected or joined to the housing 20 (e.g. by welding) and has an inner surface 120 (ref FIG. 7) and an outer surface 110 which provides a viewing...

Abstract

A lamp assembly for illuminating a ground area adjacent a vehicle is disclosed. The assembly includes a housing; an outer lens covering the housing; a plurality of light emitting diode (LED) light sources arranged in the housing; and a reflector mounted in the housing. The light emitted from the plurality of LED light sources is captured by the reflector which reflects light towards the lens, the lens directing light generally downward towards the ground area. The light output from the lamp assembly appears to be emitted from a single light source.
